The lampholders should be facing down when installed, up to a maximum of 45 degrees to help prevent water ingress. Through our extensive experience with festoon lighting as a hire company we have found Turnock Festoons to be the highest quality available with exceptional durability and longevity, they're manufactured here in the UK and w. E use these festoons in our own hire stock. These are heavy duty commercial grade black RUBBER cable strings manufactured to the highest quality suitable for domestic or professional use. This festoon is also available with Edison Screw (ES/E27) lampholders, please see the available variation listing links below.The difference between BC and ES lampholders: with both options the Festoon cable and lampholders are exactly the same in dimensions etc, it is simply the fitting inside the lampholders that will affect what lamps can be used with the Festoon. Which lampholders you require would depend on what lamps you intend to use with the festoon, different lamp types are sometimes more readily available in one lampholder type than the other so always be sure to check carefully before ordering. If your intended application for the festoon will involve tranporting it and hanging it in different places we would highly recommend removing all the lamps as you take down the Festoon cable for transport and then reinstalling them as you put it back up again. Not only will this massively help to reduce breakages particularly if the lamps are made of glass, but you will also find the Festoon cable considerably easier to handle and mount. Available variations of this length Festoon.
